BOLT NUT CUTTER.

SPECIFICATION formingipart of Letters Patent No. 790,617, dated May 23, 1905.

- Application filed March 3, 1903. Serial No. 145,882.

.T0 all Vwiz/0m it may concern; v

Beit known that I, WILLIAM B. CARoLUs, a

citizen of the United States, residing at Ster-v ling, inthe county of Whiteside and State of Illinois, have invented a new and useful Im- -provement in Bolt and Nut Cutters, of which the following is a specification.

My'invention relates particularly to combination bolt and nut cutters of the character described in my United States Patent No. 710,182, granted September 30, 1902.

My primary object is to provide Vimproved means for preventing racking or displacement of the swinging blades employed Vand also to 'provide an improved construction of the blades, permitting the use of the implement in places difiicult of access.

' The invention is illustrated in the accompa- -nying drawings, in which;

Figure l represents a broken plan view of the improved device; Fig. 2, a similar view with the top plate of the frame removed; Fig. 3, a longitudinal sectional view taken as indicated at line 3 of Fig. l; Fig. 4, a transverse sectional view taken as indicated at line 4 of Fig. l, and Fig. 5 a transverse section taken as indicated at line 5 of Fig. l.

The preferred construction is as follows: A A representa pair of swinging bolt-cutting blades pivotally joined by bolts a to 'con- `meeting-plates a a2, constituting a frame for the head of the instrument; B B', levers pivotally joined together at and connected by pivots with the base ends of the blades, and C a blade-controlling member preventing racking or displacement of the blades. The

blades are provided with cutting edges c andhave beveled surfaces c' on their upper surfaces. At their extremities the blades are provided with upturned blades d, having boltcutting'edges d. Surmounting the blades d are nut-splitting blades f, having vertical edges f f2, the latter being slightly rounded or blunt.

The plates a a2 are preferably stamped from sheet metal and are extended rearwardly a sufficient distance to house the pivotal ends of the hand-levers B B. They are provided with slots g, in which worksthe pivotal bolt 7), connecting the levers.

-are located properly to split the nut.

The member C comprises a head la, having lateral projections 7L', with roundedfsurfaces fitting in suitably-concaved bearings if, with which the blades A A are provided, and a'Y 'of a stove-top-I provide a yielding gage or stop D, which is carried by the plate a'. This comprises a shank g,connected with said plate, and an Iupturned extremity g', spaced at a suitable distance from the vertical blades of the device. The stem g is provided with a longitudinal slot g2, which is slidably connected with an adjustable block g3, secured to the plate by a screw g4, which extends through a slot in the block g3. Confined between the front edge of the block 'g3 and the front end of the slot g2 is aspring g5. This spring normally-holds the gage in its forward position,

the position being determined by the adjustment of the block g3, with the rear edge of which the rear end of the slot g2 is in normal engagement. When a nut ,is to be split, the instrument is shoved forward till'the flange g of the gage engages one edge of the nut, in which position the edges of the blades f edge f2, being somewhat blunt, acts as a pivot about which the halves of the nut turn when the nut is split by the edge f.

In use either the edges c or the edges CZ may be employed for clipping a bolt, according to convenience. edges f' f2 are employed as described. In the closed position of the blades the edges f f2 are separated by a space corresponding with the diameter of the bolt. The member C acts to aid the pivots c in preventing separation of the blades and also acts to prevent one blade from Working forward with relation to the other, the stem of the member C The In splitting a nut the being prevented from turning by reason of the connection with the guides h5, which guides permit the necessary relative movement between the member C and the plates a a2.

While I have shown the nut-splitting blades formed integrally with the bolt-cutting blades, it is obvious that they may be separately formed and may bev adjustable with relation to the bolt-cutting blades.

Changes in minor details of construction within the spirit of my invention may be made. Hence no undue limitation should be understood from the foregoing detailed description.

What I regard as new, and desire to secure byLetters Patent, is-

y1. An implement of the character described, comprising pivoted blades with cutting edges lying in one plane and nut-splitting blades at right angles to and carried by the extremities of said first-named blades, and having their splitting edges in the closed position separated by a space for the bolt, for the purpose set forth.

2. An implement of the character described, comprising pi-voted bolt-cutting blades with cutting edges lying in one plane, bolt-cutting blades at right angles to and carried by the extremities of said first-named blades, and nut-splitting blades adjacent to said secondnamed blades and at right angles to said firstnamed blades.

3. Animplementof the character described,

comprising swinging blades, a frame in which saidblades .are pivoted, hand-levers connected with said blades, and a member interposed between said blades having bearings therein and movably connected with said frame, for the purpose set forth.

4E. An implement of the character described, comprising swinging blades, a frame in which said blades are pivoted, hand-levers connected with said blades, and amember interposed between said blades having bearings therein and provided with a projecting stem slidably connected with said frame.

5. An implement of the character described, comprising swinging blades, a frame in which said blades are pivoted, hand-levers connected with said blades, and a member interposed between said blades and provided with conveX enlargements fitting within cavitles 1n the adjacent portions of said blades and tending to prevent separation of the blades and longitudinal movement of the blades with relation to each other.

6. An implement of the character described, comprising suitable plates, blades between said plates and pivoted therein, hand-levers pivoted between said plates and connected by a pivot slidably connected with said plates, and. a member confined between said blades and said plates and having bearings in the blades between the pivots thereof and provided with a stein slidably connected with a plate, for the purpose set forth.

7 An implementof the character described, comprising pivoted cutting-blades, cuttingblades carried thereby and projecting at right angles thereto, means for operating` the blades, and a suitably-su pported gage adjacent to said second-named blades and on the side thereof towardithe base ends of the first-named blades, for the purpose set forth.

8. An implement of thel character described, comprising a suitable frame, blades pivoted therein, hand-levers for actuating said blades, blades at right angles to said lirstnamed blades and carried by the extremities thereof, and a gage yieldingly supported on said frame, for the purpose set forth.

9. In an implement of thc character described, the combination of two suitablyspaced plates provided with a longitudinal guide, blades between said plates and pivoted thereto, amember located between said blades and having bearing connections therewith between the pivots thereof and provided with a 'stem slidably connected with said guide, and

hand levers pivotally connected with said blades and connected by a pivot moving in longitudinal guides in said plates, for the purpose set forth.

10. An implement of the character described, comprising a frame with suitable sides, blades between and pivoted to said sides, hand-leversjoined to said blades by pivots confined by said sides, and a pivot connecting said hand-levers and moving in guides in said sides.
